[0029] Example 1

[0030] like Figures 1-3 As shown, the rotor vibration damping mechanism of the air conditioner outlet actuator is used on the rotor of the actuator. The rotor includes the rotor body and the rotating shaft 5 inside the rotor body.

[0031] To reduce noise, a vibration damping mechanism is provided between the rotating shaft 5 and the rotor body.

[0032] The vibration damping mechanism includes an inner rotor 1, a clamping structure, and a vibration damping pad 3. The inner rotor 1 is made of plastic and is located inside the rotor body, between the rotor body and the rotating shaft 5. The rotor body is the rotor magnet 2, and the rotor magnet 2 and the inner rotor 1 are designed as a single unit to achieve the best synchronization without any gaps.

[0033] The clamping structure includes a clamping cavity 6 located at the lower part of the inner rotor 1. A clamping assembly is provided within the clamping cavity 6, which clamps the rotating shaft 5. The clamping assembly consists of three clamping plates 4 arranged in a petal-like pattern. One side of each clamping plate 4 clamps the rotating shaft 5, while the other end rests against a vibration damping pad 3. In this embodiment, the petal-shaped clamping plates 4 are integrally designed and manufactured with the inner rotor 1.

[0034] The damping pad 3 is arranged on the inner side of the holding cavity 6 and abuts against the holding plate 4. A bushing is arranged between the damping pad 3 and the holding plate 4. The bushing between the holding plate 4 and the damping pad 3 ensures the fitting size gap, which not only facilitates the installation, but also improves the durability noise performance.

[0035] The damping pad 3 is made of elastic material with small thermal deformation coefficient, which is not limited to rubber or metal spring. The damping pad 3 compresses the holding plate 4 under the inner rotor 1 to make the holding plate 4 deformed, holds the rotating shaft 5 and provides appropriate force value to ensure the contact between the inner rotor 1 and the rotating shaft 5.

[0036] After the motor of the actuator is powered on, the inner rotor 1 rotates around the rotating shaft 5 under the electromagnetic force of the rotor magnet 2. The top of the inner rotor 1 is provided with a gear, and the gear is engaged to transmit the torque and rotating speed to the output end of the actuator.

[0037] The holding plate 4 with the petal structure at the lower part of the inner rotor 1 is compressed by the damping pad 3, so that the holding plate 4 is deformed to hold the rotating shaft 5 and provide appropriate force value to ensure the contact between the inner rotor 1 and the rotating shaft 5. This not only avoids the phenomenon of jamming caused by excessive compression force, but also solves the noise phenomenon caused by the deviation of coaxiality or meshing impact.

[0038] Embodiment 2

[0039] Compared with embodiment 1, the difference between embodiment 2 and embodiment 1 lies in the structure between the inner rotor 1 and the holding plate 4.

[0040] As shown in Figure 1 , Figure 4 , Figure 5 , the inner rotor 1 and the holding plate 4 in embodiment 1 are an integral whole, but the holding plate 4 and the inner rotor 1 in embodiment 2 are separate.

[0041] In this embodiment, the holding plate 4 is designed and manufactured separately and arranged in the holding cavity 6 in the form of petal. A petal bushing is arranged between the damping pad 3 and the holding plate 4.

[0042] The bushing between the holding plate 4 and the damping pad 3 ensures the fitting size gap, which not only facilitates the installation, but also improves the durability noise performance.

[0043] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses or adaptations of the application including variations of the application that are readily apparent to those skilled in the art and includes the generic principles defined herein and the best mode for carrying out the application. It is intended to include what is claimed and any equivalents thereto.

[0044] It is to be understood that the present application is not limited to the precise construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the present application. The scope of the present application is limited only by the appended claims.
